Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a noncombustible panel used for the interior of buildings, etc., and a method for manufacturing the same.

[Prior Art] As shown in FIGS. 13 to 15, in a conventional noncombustible panel of this type and a method for manufacturing the same, a core material 1 made of an aluminum sheet or an asbestos honeycomb core is coated with steel or steel on both sides. It is made of stainless steel and has surrounding rising parts 2a and 3b.
Metal surface plates 2 and 3 on which are formed, respectively, are adhered with an adhesive with the rising portions 2a and 3a facing each other (as shown in Figure 13), and the manufacturing method thereof is as follows: Rising portions 2 of the metal surface plates 2 and 3 that are moved while being suspended
Adhesive is applied by spray 5 to one surface where a, 3a are projected, and then one metal surface plate 3 is applied.
is placed on the plywood 6 with the surface coated with adhesive facing upward, and the core material 1 is placed on the metal surface plate 3. Next, place the other metal surface plate 2 on the other surface of this core material 1 with the side coated with adhesive facing down, and press from above to place both metal surface plates 2 and 3 on each surface of the core material 1. It is manufactured by crimping.

[Problems to be Solved by the Invention] Conventional non-combustible panels and their manufacturing methods are as described above, so (1) when cutting the resulting non-combustible panels, shock and vibration from a jigsaw etc. Because it is transmitted to the metal surface plates 2 and 3 and the core material 1,
The metal surface plates 2 and 3 are likely to peel off, (2) the heat insulation and sound insulation properties of the core material 1 alone are low, and (3) when applying adhesive to the metal surface plates 2 and 3, the metal surface plates 2 , 3 are formed around the metal surface plates 2a, 3, it is difficult to apply it only with the spray 5, and in addition, the coating becomes uneven and has poor retention, and the surfaces of the metal surface plates 2, 3 may also become dirty. (4) Due to the unevenness of the surface of the core material, it is difficult to apply pressure uniformly when assembling the metal surface plates 2 and 3, and there is a problem that perfect crimping cannot be achieved.

[Means for Solving the Problems] This invention has been made in view of the above-mentioned circumstances, and its outline is that a non-flammable or flame-retardant honeycomb core or a thickness direction A noncombustible panel is formed by sandwiching a core material having a large number of holes on its entire surface, and a noncombustible soft inorganic plate is interposed and fixed between at least one of the metal surface plates and the core material. One side of a non-flammable soft inorganic plate, which has been passed between a pair of rolls and evenly coated with adhesive on both sides, is pasted to the opposing sides of one of the metal face plates of the face plate, and this soft inorganic plate On the other side, one side of a non-flammable or flame-retardant honeycomb core or a core material having holes in the thickness direction is pasted on the other side of the core material so that the holes of the honeycomb core etc. are in the thickness direction. Then, the other metal surface plate is attached either directly or through a non-flammable soft inorganic plate uniformly coated with adhesive by passing it between the rolls, and pressure is applied in the direction in which these plates are stacked. It is an object of the present invention to propose a noncombustible panel and a manufacturing method thereof, which can solve the conventional problems by manufacturing the above-mentioned members by pressing them together.

[Embodiment] An embodiment of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a perspective view showing a noncombustible panel of the present invention. In the drawing, 11 indicates a core material, and the core material 11
As shown in Figures 2 to 4, it is made of asbestos or aluminum thin plate and has a honeycomb core shape (second
(as shown in the figure), a lattice shape (as shown in the third figure), or a large number of holes 1 formed by alternately arranging flat plates and corrugated plates in a laminated manner.
2 is formed over the entire surface in the thickness direction.

Both sides of the core material 11 are covered with flexible soft inorganic boards 13, 1 such as asbestos calcium carbonate foam board.
4 is attached via adhesive. Then, adhesive is applied to both outer surfaces of both inorganic plates 13 and 14.
Metal surface plates 15 and 16 made of a steel plate, a stainless steel plate, or an aluminum plate are adhered to each other, and rising portions 15a and 16a are respectively formed around the metal surface plates 15 and 16 to protrude toward the opposing side.
The peripheries of both the soft inorganic plates 13 and 14 are covered and held by these rising portions 15a and 16a, respectively.

The noncombustible panel of the present invention may have a structure in which the soft inorganic plate 14 is interposed only on one side of the core material 11, as shown in FIG. Soft inorganic board 13,1
4 and the metal surface plates 15, 16 are attached to the ends thereof, a shaped member 17 having a U-shaped cross section is attached, and the rising portions 15a, 16 of the metal surface plates 15, 16 are attached.
It is also possible to have a structure in which the winding is stopped by a.

Next, as shown in FIGS. 7 to 12, the method for manufacturing a noncombustible panel of the present invention begins with a seventh step.
In the figure, the soft inorganic plates 13 and 14 are passed between a pair of rollers 18 and 19 to which adhesive is applied, and the adhesive is uniformly applied to both surfaces thereof. On the other hand, as shown in FIG.
The one metal surface plate 16 on which is erected is the plywood 2
0 with the rising portion 16a facing upward.

Next, as shown in FIG. 9, one of the soft inorganic plates 14 with adhesive applied on both sides is placed on top of this metal surface plate 16 so that one side with adhesive applied is in close contact with the other soft inorganic plate 14. It will be posted on.

Next, as shown in FIG. 10, the soft inorganic plate 14
The core material 11 is applied to the other surface coated with the adhesive.
is placed so that the holes 12 formed in large numbers are in the thickness direction.

Then, as shown in FIG. 11, the other soft inorganic plate 13 is
The metal surface plate 15 attached to the top plate is placed on the other surface of the core material 11, and as shown in FIG. By pressing, the noncombustible panel of the present invention can be manufactured.

In the noncombustible panel of the present invention in which the soft inorganic plate 14 is interposed only between the one metal surface plate 16 and the core material 11, from the state shown in FIG. 11 through adhesive, and then the plywood 21
Pressure is applied in the direction in which the members are stacked, and each member is adhered.

[Effects of the Invention] As described above, the noncombustible panel and the method for manufacturing the same according to the present invention have the following effects.

(1) Due to the buffering effect of the soft inorganic board and the anchoring effect caused by the irregularities on the surface of the core material biting into the soft inorganic board, the metal surface board is unlikely to peel off when cutting this noncombustible panel. cutting process is easier.

(2) Since the soft inorganic board is interposed, the heat insulation and sound insulation properties are further improved.

(3) Since the adhesive can be applied to both sides of the soft inorganic plate using a roller, the application is uniform without waste, the yield is good, the speed can be increased, and the productivity of the panel is improved. Furthermore, since there is no need to apply adhesive to the metal surface plate, the metal surface plate is not contaminated.

(4) The soft inorganic board acts as a cushioning material, the pressure applied by the plywood becomes uniform, and the unevenness on the surface of the core material bites into the soft inorganic board, improving adhesiveness and strength, so that almost perfect crimping can be achieved.
